Turning Spring Effects On/Off

In iClone, Spring Effects of characters or props that contain bone-structures can be turned on or off, so that the bones can sometimes auto-animate along with the motions of the characters or props and other times be manually animated by key-frame-editing with IK / FK methods.

Turning Spring Effects On/Off

1. Load a character or a prop with spring effects on specific bones (in this case, the character has been given spring effects on the ears and the tail bones).
   
2. Apply motions to the character, you can see the spring effect triggers the bones to auto-bounce.

3. Make sure the character is selected and go to a specific time frame when you want to turn off the spring effect.
4. In the Spring section of the Modify panel, select the bones for which you want to turn the spring effects off via the Select Spring drop-down list.
   
5. Press down the Off button.
   
6. Go to another time frame, click the On button to turn the spring effect on again.
7. Play back to view the result of the different spring effect settings.

   Note:

   The Spring keys can be found in the character or prop's Spring track in the Timeline. Please refer to the Spring Track section for more information.
